For air purifiers, it is necessary to choose pure physical filtration with three correct views

　　What is a pure physical air purifier?

　　First of all, the graduates who represent the chemistry field stated that the so-called "pure physics" is typical, and it promotes discrimination in the discipline of society. The so-called impure physical emptiness still uses physical technology.

　　Well, commonly known as pure physical filtration, it refers to only filtering with HEPA, activated carbon and other filters to remove PM2.5, formaldehyde and other pollutants in the air.

　　Relatively non-pure physical air cleaning refers to the use of no filter, or the use of other technologies in addition to the filter, such as the recently popular high-voltage electrostatic dust collection technology, and of course, there are various strange things that Japanese manufacturers may fabricate. Name the technology, such as X ion, X factor, XX energy and so on.

　　Why is "pure physics" correct in the three views?

　　Purely physical air purification, using HEPA filter + activated carbon, is the most mature technology among air purification products at present, but there is a disadvantage that the price is too transparent-it is clear at a glance what grade of product, cost, and price are used. , As long as ordinary users can compare the numbers, they can simply do a horizontal comparison to evaluate which product is more cost-effective and which is more black-hearted. How can electrical manufacturers tolerate such a lack of initiative?

　　The reason why manufacturers use similar electrostatic technology, in addition to fabricating gimmicks, is mostly to achieve higher and more beautiful purification values without increasing costs. You can spend less money, use less filter elements, and don't have to worry about the noise of the motor.
